FLOAT-OPERATED VALVE.

Specification of Letters Patent.

To all .whom t ma? concern.'

Be it known ti'at. I, JOHN W. WALL, a citizen of the United States,residing at Bisbee, in the count-y of Cochise and State of Arizona, haveinvented certain new and useful Improvements in Float -Operated Valves;4and Ido declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in float operated valves.

One object ofy the invention is to provide a valve of this characterhaving an improved construction and arrangement of operating leverswhereby the valve will be positively opened upon the discharge of thewater from and the lowering of the iioat in the tank to which the' valveis applied.

Another object is to rovide a fioat 0perated valve which wil be sim le,strong and durable in construction, e ient and reliable in operation andwell adapted to the pur ose for which it is designed. ith these andy'other ob'ects in view, the invention consists of. certain novelfeatures of construction and the combination and arran ement of parts aswill be more fully descri ed and claimed. l

In the accompanyingA drawings; Figure 1 is a vertical section of myimproved valve showing the same applied to a tank and in closedposition; Fig. 2 is a similar view showing the valve in open position;Fig. 3 is a plan view of the same; Fig. iis a perspective view of thevalve operating plunger; Fig. 5 is a cross sectional view of the same.

Referring more 'particularly to the drawings, 1 denotes the tank towhich my improved valve is applied.Y In the bottom of the tank near oneend is arranged a valve casing 2 the lower---end of which projects asuitable distance below the tan and is threaded to receive the couplingof the water supply pipe of the tank. The upper i. end of the valvecasing 2 projects a suitable distance above the bottom of the tank 1 andis threaded to receive a plungerA casing 3 which is screwed thereon andinto engagement with the bottom of the tank. The lower end of the .iplunger casing 3 has thereon an annular radially projecting `bottom ofthe tank and forms a screwed onto the upper end of the valve casingclosely engages or bindsv Gainst the qiiluid tight en agement betweenthe inner end of the va ve casing and said bottom of the tank. Clam edbetween the end of the valve casing 2 an the inner end of .the socket'in the plunger casing with which the end ofthe On one side of theplunger casing'is a" Water discharging spout 9 above which the plungercasing is reduced to form a plunger guiding socket 10. In the plungercasing 3 immediatel below the spout 9 and on the upper end o the socketof the plunger casing which receives the inner end of the valve casingis an upwardly projecting plunger guiding iiange 11. 'Arranged in theplunger casing 3 is a valve opening plunger 12 the lower end oi which isslidably engaged with the flange v11 while the upper end thereof isslidably engaged with the plunger guiding socket 10 on the upper end ofthe plunger casing. The upper end of the plunger 12 which engages theguide socket 10 is preferably of cylindrical forni while the lower endis constructed in ,thev form 0f a Greek cross, the outer edges of thearms of which slidably engage the flange 11 ,and provide openingsthrough which Water may pass 'into the plunger casing and out throughthe discharge spout when the valve 6 is opened.

In the upper end of the plunger 12 is a transverselydisposed slot 13 inwhich is engaged the inner end of a plunger operating lever 14 which ispivotally mounted belange 4 which when the plunger casing is` PatentedDec. 1 7, 1912.

tween'a pair of bearing lugs 15 on one side n Log/,see

plunger whereby when the lever 14 is rocked in the proper direction theplunger 12 will be forced downwardly thus depressing the valve 6 anddisengaging the saine from the seat in the washer 5 thereby permittingthe Water froin the supply pipe to pass through the valve casing andplunger casing into the j tank.

On the outer end of the discharge spout 9 is a pair of upwardlyprojecting apertured bearing lugs 18 to which is pivotally connected theangularly formed or V-shaped inner end 19 of a iioat rod oil lever 20onthe outer end of which is secured a oat 2l which is adapted to riseand fall with the rise and fall of the water in the tank. The

apex or point of the rod or lever 2O is connected by a short link 22with the outer end vof the plunger operating lever 14 whereby when thewater is discharged from the tank and the iioat 21 is thus lowered theinner end of the float rod or lever 20 will, through the link 22, swingthe outer end of the plunger operating lever 14 upwardly and the innerend thereof downwardly in the socket 10 of the plunger casing therebydepressingthe plunger and causing the sanie to open the valve 6 in thenianner described. After the water has been discharged from the tankings, the construction and operation of the invention will be readilyunderstood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as claimed.

Having thus described lmy invention', what I claim is:

In a float operated valve for tanks, a valve supply pipe connection, aplunger casing engaged with the inner end of said valve casing andforming a` fiuid tight connection be- Acasing` arranged in the/bottoni'of the tank 50 and projecting below' the saine to forin a tween thevalve casing and the bottom of the tank, a washer arranged between saidvalve casing and plunger casing/said washer having therein a. valveseat, a valve arranged in said valve casing, a spring to normally holdsaid valve in engagement with said seat,

a plunger guiding socket on the upper end of said plunger casing, aplunger guiding flange arranged in said casing, a plunger slidablymounted in said socket and flange and having its lower end engaged withthe valve whereby when the plunger is depressed the valve will beopened, a discharge spout on said plunger casing, a plunger operatinglever pivoted on said socket and having its end projecting into thesaine and lengaged with said plunger, a float rod having an angularinner end pivotally connected at the end to said spout, a link toconnect the apex of said angular inner end of the valve rod with theouter end of said plunger operating lever and a float carried by theouter end of said ioat rod whereby v when said float is lowered by thedischarge of the water from the tank said lever vwill be actuated todepress said plungerand thereby open said valve and whereby when thetank fills and the oat rises, said lever will be actuated to permit thevalve operatingspring to close the valve.

In testimony whereof I have hereunto 8 set my hand in presence of twosubscribing witnesses.
